编写要求：

请老师在出现黄柱（抄底）的地方做个选股公式，谢谢！ 趋势:5*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1) -3*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1) -SMA(SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1) ,3,1),2,1),COLOR7F52AF; 底部:5; 抄底:IF(CROSS(趋势,底部),60,0),STICK,COLORYELLOW,LINETHICK4;

解答：

?趋势:=5*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-3*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1)-SMA(SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1),2,1);

底部:=5;
